A carbon atom has four valence electrons. How do all living things depend on this property and other special chemical properties of the carbon atom?
Answer:
It is for the fact that Carbon need to fill up its shell for order to make it coplete. Hense using Covelant bonds. Carbon therefore can connect to oxygen, hygrogen, and other carbon molecules. Also Carbon can connect in 4 ways to. It also can form 2 main covelant bonds
Explanation:
I am a bio teacher
Carbon is an element with four valence electrons which makes it possible to
form covalent bonds with other elements such as Hydrogen, oxygen etc.
Carbon has four valence electrons and needs an additional four in order to
achieve a stable octet configuration. This makes it react with other
elements . When an element has fewer or no valence electrons in the outer
shell, it becomes less reactive to ensure the stable configuration isn't altered.
This is why carbon is able to pair electrons with other elements through
covalent bonding to ensure that the octet configuration is achieved.

Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another. Thus, option 1. C, 2. A , 3. D, 4. B is correct.
What are different phases of matter?Depending on the pressure and temperature circumstances, a given set of matter can change its state or phase, transitioning to different phases as these variables change to favor their existence.
The primary distinction between a substance's phase and state can be summed, For instance, a solid can convert to a liquid when the temperature rises.
A substance's phase describes its uniform chemical and physical qualities, whereas a substance's state describes its shape at a specific temperature and pressure.
Therefore, A phase change from a solid to a liquid represent melting.

E.Coli is a type of prokaryotic bacterium that is present in contaminated food. Which describes where the genetic material is found
A.cytoplasm
B.Cell membrane
C.Ribosome
D.Nucleus
Answer:
Cytoplasm
Explanation:
In prokaryotes DNA is located directly within the cellular cytoplasm
In the E.coli, that is, a prokaryotic bacterium, the genetic material is found in the cytoplasm.
The genetic material in E.coli:E.coli is a prokaryotic bacterium, and in all the prokaryotic cells, genetic information is carried on a single circular strand of DNA, which is either present in direct contact with the cytoplasm or is attached to the cell membrane.
In the prokaryotes, no enclosing membrane organelle is present, therefore, no nucleus is found. They comprises a concentration of DNA called nucleoid, which is not encircled by a nuclear membrane. Apart from this, no unique proteins are found attached with the molecule of DNA.
Thus, the correct answer is option A, that is, cytoplasm.

Which structural component is found in DNA but not in RNA?
O ribose
O deoxyribose
O phosphate group
O nitrogenous base
Answer:
Deoxyribose
Explanation:
Neither deoxyrinose nor thymine is found in RNA.
The structural component found in DNA but not in RNA is deoxyribose.
What is DNA and RNA?Both DNA and RNA contain the same nitrogenous bases (adenine, guanine, cytosine, and uracil in RNA or thymine in DNA) and phosphate groups.
However, DNA contains deoxyribose sugar in its backbone, while RNA contains ribose sugar. The difference between the two sugars is that deoxyribose lacks an oxygen atom on the second carbon in the sugar ring, whereas ribose has an oxygen atom at that position. This difference in sugar composition is responsible for some of the unique properties of DNA, including its double-stranded helical structure and greater stability compared to RNA.

4 – Microwave Miracle Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each. What was Patrick’s hypothesis? Which fish are in the control group? What is the independent variable? What is the dependent variable? Look at the results in the charts. What should Patrick’s conclusion be?
Answer and Explanation:
What was Patrick’s hypothesis? Fishes that are fed with food exposed to the microwave will become smarter and will swim faster. Which fish are in the control group? The ones that feed on regular food What is the independent variable? Food exposed to the microwave What is the dependent variable? The time fishes spend in swimming through the mazeWhat should Patrick’s conclusion be? You will find the results considered in the attached file.In both groups, Patrick recorded a decrease in the time spent swimming through the maze. In both groups, there were two cases in which the animal increase the swimming time. These cases could be considered as outliers. Although in general, the treated group made it in a shorter time after the treatment, when comparing values before and after Patrick can not find any real difference among groups. His results do not show any difference, hence the speed and the intelligence of the animals is not influenced by the change in food, or if it is, more experimental time is required to record significant differences.

Which of the following is not controlled at the individual level?
Response
Genetic code
Growth and development
Evolution
Answer:
Evolution
Explanation:
Evolution is the change that occurs to a particular species of a population from generation to generation. This change is due to the alteration in their genetic composition, which is inherited over time.
However, this change do not occur at the individual level but rather it occurs to a population i.e. only a POPULATION undergoes evolution process not individual organisms. Note that, the other options including genetic code, growth and development, response are controlled individually by the organism, however, the evolution process takes time and occurs over a population rather than to individuals

If 30% of the nucleotides in a single-stranded RNA molecule are adenine, then what percent are expected to be thymine?
Answer:
Explanation:
the base pair of adenine is thymine they are equal in amount in RNA so if 30% of the nucleotide in RNA is adenine so the percentage of thymine would also be equal to adenine that is 30%
If the DNA strand has 30% Adenine in its composition, it means that the same DNA strand has 30% thymine in its composition.
This is because:
DNA is composed of the nitrogenous bases Adenine, Thymine, Cytosine and Guanine.These nitrogenous bases were paired with each other.Adenine pairs with Thymina. While Cytosine pairs with Guanine.Therefore, the amount of Adenine and Thymine in a DNA must be equal. While the amount of Guanine and Cytosine must be equal.In this case, we can conclude that if the DNA has 30% of Adenine, it is mandatory that this same DNA has 30% of Thymine.

Explanation:
The similar shapes of fast swimming marine predators are an example of convergent evolution.
Convergent evolution shows how different species possess identical structures even though they evolve separately. Convergent evolution typically takes place with the organisms that are not really related.
